Abstract

The clip is suitable for attaching electric cables of various diameter to perforated sheet metal. The clip is manufactured from a flexible plastic and has a lightly arched top (7) which is thickened to clamp the top of the cable. The sides of the clip are thinner and form a double 'S' shape (2) which provides flexibility and, on its inner prominences (2b), holds the cable laterally. The lower portion is thickened and is split, with a projection on each side of the split shaped so that when the split is closed the projection forms a short cylindrical column surmounted by a cone (4). The cone is forced through the hole in the sheet metal and when the split springs open the shoulder formed by the cone base (6) is lodged behind the metal.

Description

ta présente invention a pour objet une agrafe pour gaines de diamètres multiples, notamment pour la fixation de connexions électriques sur des tôles de support dans des véhicules automobiles et des machines a usage électroménager, telles que des machines à laver. Pour fixer cur des tôles de support des tubes ou des gaines électriques darus les véhicules ou les machin-## d'électroménager, on utilise habituellement des agrafes constituées par un collier dont les branches peuvent s'écarter élastiquement pour enserrer le tube ou la gaine, et qui ont le même diamètre que celles-ci. les extrémités libres des branches de lwagrafe sont munies de griffes d'accrochage sur le support, susceptibles d'être introduites à cet effet dans un trou de ce dernier. Your present invention relates to a clip for sheaths of multiple diameters, in particular for fixing electrical connections on support sheets in motor vehicles and machines for household appliances, such as washing machines. To fix the support plates of tubes or electrical sheaths in vehicles or household electrical appliances, staples are usually used, made up of a collar, the branches of which can move elastically to enclose the tube or sheath. , and which have the same diameter as these. the free ends of the branches of the clip are provided with hooking claws on the support, capable of being introduced for this purpose into a hole in the latter.

Ainsi, à chaque gaine à fixer sur une tôle de support correspond une agrafe de même section, de sorte qu'il faut autant d'agrafes que de gaines de sections différentes pour assurer la fixation de celles-ci sur les tôles. Thus, to each sheath to be fixed on a support sheet corresponds a staple of the same section, so that as many staples as there are sheaths of different sections are required to ensure the fixing of these on the sheets.

L'invention a pour but de remédier à cette con- trainte en réalisant une agrafe eCeneée de telle manière qu'eli- le puisse assurer la fixatio indifféremment de plusieurs gaines de diamètres différents. The object of the invention is to remedy this constraint by producing an eCeneee staple in such a way that it can fixate several sheaths of different diameters indifferently.

Conformément à l'invention, les branches élastiques de l'agrafe sont ondulées ou repliées en accordéon, afin de pouvoir se déployer élastiquement autour de gaines de diamètres différents. According to the invention, the elastic branches of the clip are wavy or folded in accordion fashion, in order to be able to deploy elastically around sheaths of different diameters.

Chaque branche présente donc au moins deux plis ou ondulations qui peuvent se détendre ou se déployer élastiquement pour s'adapter au diamètre de la gaine à fixer à la tôle de support. Ainsi, on peut au moyen d'une seule agrafe selon l'invention assurer la fixation d'une gamme de gaines ou tubes de diamètres multiples, ce qui simplifie le montage des gaines et diminue le coût de fabrication des agrafes. Each branch therefore has at least two folds or undulations which can relax or deploy elastically to adapt to the diameter of the sheath to be fixed to the support sheet. Thus, it is possible by means of a single clip according to the invention to secure a range of sheaths or tubes of multiple diameters, which simplifies the mounting of the sheaths and reduces the cost of manufacturing the staples.

D'autres particularités et avantages de l'invention apparaitront au cours de la description qui va suivre~. Other features and advantages of the invention will become apparent during the description which follows ~.

Aux dessins annexés, on a représenté une forme de réalisation non limitative de l'invention. The accompanying drawings show a non-limiting embodiment of the invention.

- La figure I est une vue en perspective d'une forme de réalisation de l'agrafe selon l'invention. - Figure I is a perspective view of an embodiment of the clip according to the invention.

- La figure 2 est une vue en élévation à échelle agrandie de l'agrafe de la figure 1. - Figure 2 is an elevational view on an enlarged scale of the clip of Figure 1.

- La figure 3 est une vue ml-coupe, mi-élévPtion représentant l'agrafe montée sur une gaine dont elle assure la fixation à une tôle de support. - Figure 3 is a ml-sectional view, mid-elevation showing the clip mounted on a sheath which it ensures attachment to a support plate.

l'agrafe représentée aux figures 1 à 3, est destinée à assurer la fixation, avec d'autres agrafes similaires, de gaines de diamètres multiples, par exemple de connexions électriques sur des tôles de support dans les véhicules automobiles ou les machines à usage électroménager telles que les machines à laver. the clip shown in Figures 1 to 3, is intended to ensure the attachment, with other similar clips, sheaths of multiple diameters, for example electrical connections on support sheets in motor vehicles or machines for household appliances such as washing machines.

L'agrafe 1 comporte deux branches 2 adaptées pour enserrer élastiquement une gaine 3, et qui sont terminées chacune par une griffe 4 d'accrochage sur une tôle de support 5. Chaque griffe 4 est pourvue d'un ressaut extérieur ou redan 6, qui vient s'encliqueter sur le bord d'un trou10 de la tôle 5 dans lequel viennent s'introduire les griffes 4 lorsque l'agrafe 1 est montée sur la gaine 3 à fixer, comme on le voit à la figure 3. The clip 1 comprises two branches 2 adapted to elastically enclose a sheath 3, and which are each terminated by a claw 4 for attachment to a support plate 5. Each claw 4 is provided with an external projection or step 6, which just snaps onto the edge of a hole 10 in the sheet 5 into which the claws 4 are introduced when the clip 1 is mounted on the sheath 3 to be fixed, as seen in FIG. 3.

Suivant l'invention, les branches élastiques 2 sont ondulées ou repliées en accordéon, afin de pouvoir se déployer élastiquement autour de gaines de diamètres différents. Dans l'exemple d'exécution illustrée aux dessins, chaque branche 2 est ainsi constituée de deux plis ou ondulations successives 2a, la première ondulation étant raccordée à la base de la griffe 4 correspondante, tandis que la seconde ondulation est reliée à une partie intermédiaire 7 dont l'ép is6eur est supérieure à celle des branches ondulées 2. La partie 7 du collier constitué par l'agrafe 1 est en effet destinée à recevoir la poussée de la gaine 3 reposant sur les bases des griffes 4, comme on le voit à la figure 3. According to the invention, the elastic branches 2 are wavy or folded in accordion fashion, in order to be able to deploy elastically around sheaths of different diameters. In the exemplary embodiment illustrated in the drawings, each branch 2 thus consists of two successive folds or undulations 2a, the first undulation being connected to the base of the corresponding claw 4, while the second undulation is connected to an intermediate part 7, the thickness of which is greater than that of the corrugated branches 2. The part 7 of the collar constituted by the clip 1 is in fact intended to receive the thrust of the sheath 3 resting on the bases of the claws 4, as can be seen in Figure 3.

L'agrafe 1 peut être constituée en une matière élastique convenable, par exemple une matière plastique telle qu'un polyamide, ou le polyéthylène, ou le polypropylène, ou encore un métal élastique tel qu'un acier à ressort. The clip 1 can be made of a suitable elastic material, for example a plastic material such as a polyamide, or polyethylene, or polypropylene, or even an elastic metal such as a spring steel.

L'agrafe comporte encore, entre la griffe 4 et la première ondulation 2a de chaque branche 2, une lèvre élastique 8 s'étendant transversalement. La lèvre 8 est adaptée pour venir prendre appui sur la tôle support 5 lorsque les griffes 4 sont introduites dans l'ouverture 6 et encliquetées sur le bord de la tôle 5 (figure 3). The clip also comprises, between the claw 4 and the first corrugation 2a of each branch 2, an elastic lip 8 extending transversely. The lip 8 is adapted to come to bear on the support sheet 5 when the claws 4 are introduced into the opening 6 and snapped onto the edge of the sheet 5 (Figure 3).

On comprend que l'agrafe i ainsi réalisée peut s'adapter à plusieurs gaines de sections différentes. Dans la position représentée en trait plein à la figure 2, l'agrafe i, dont les griffes 4 sont légèrement écartées l'une de l'autre, n'est pas sous tension, de sorte que ses branches 2 dCtendues,- présentent les ondulations 2a. It is understood that the clip i thus produced can adapt to several sheaths of different sections. In the position shown in solid lines in Figure 2, the clip i, whose claws 4 are slightly spaced from each other, is not under tension, so that its branches 2 dCtendues, - have the ripples 2a.

Dans cette configuration, l'agrafe peut assurer la fixation d'une gaine telle que 3 (figure 3) dont le diamètre correspond sensiblement à la distance entre les raccordements 2b entre les ondulations 2a (distance référencée d sur la figure 3).In this configuration, the clip can secure a sheath such as 3 (FIG. 3), the diameter of which corresponds substantially to the distance between the connections 2b between the corrugations 2a (distance referenced d in FIG. 3).

Si maintenant on introduit dans l'agrafe 1, par écartement des griffes 4, une gaine de diamètre supérieur à d,on provoque un déploiement partiel des plis ou ondulations 2a, au terme duquel ceuxrci enserrent élastiquement la gaine à fixer à la tôle 5. En augmentant le diamètre de la gaine, on peut à la limite assurer la fixation d'une gaine dont le diamètre est tel que pour enserrer cette gaine, les branches 2 doivent être complè- tement déployées (position illustrée en traits mixtes et référencée la à la figure 2). If now a sheath of diameter greater than d is introduced into the clip 1, by spacing the claws 4, a partial deployment of the folds or corrugations 2a is made, at the end of which the latter enclose the sheath to be fixed elastically to the sheet 5. By increasing the diameter of the sheath, it is ultimately possible to fix a sheath whose diameter is such that to enclose this sheath, the branches 2 must be fully deployed (position illustrated in dashed lines and referenced 1a). Figure 2).

On peut donc au moyen d'une seule agrafe selon l'invention fixer des gaines électriques ou des tubes dont les diamètres s'étendent sur une gamme prédéterminée, correspondant au diamètre maximum de l'agrafe après déploiement complet des ondulations 2a de ces branches. De ce fait, la gamme d'agrafes différentes nécessaires pour assurer la fixation de toute une série de gaines de diamètres différents est considérablement réduite, ce qui simplifie le montage des gaines et réduit le prix de revient de la fabrication de l'ensemble des agrafes. It is therefore possible by means of a single clip according to the invention to fix electrical sheaths or tubes whose diameters extend over a predetermined range, corresponding to the maximum diameter of the clip after complete deployment of the corrugations 2a of these branches. As a result, the range of different staples required to secure a whole series of sheaths of different diameters is considerably reduced, which simplifies the assembly of the sheaths and reduces the cost price of manufacturing all the staples. .

Bien entendu l'invention n'est pas limitée à la forme d'exécution décrite et peut comporter des variantes de réalisation. Il est ainsi évident que le nombre d'ondulations 2a des branches élastiques peut varier, en fonction de la gamme de sections que doit couvrir l'agrafe.  Of course, the invention is not limited to the embodiment described and may include variant embodiments. It is thus obvious that the number of undulations 2a of the elastic branches can vary, depending on the range of sections which the staple must cover.
